Specification of Letters Patent. Patented J uly 2, 1912. lpplication filed October 9, 1911. Serial No. 653,594.

To all whom it may concern: Be it known that I, JOHN H. BLAKE,

'citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Tire-Tool, of which the following is a specification.

The device forming the subject-matter of this application, is a tool adapted to be employed for placing pneumatictires upon vehicle rims, and for removing the tires from the rims.

lVith-the foregoing and other objects in view, which will appear as the description proceeds, theinvention resides in the combination and arrangement'of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be'made within the scope of what is claimed without departing .from the spirit of the invention.

In the drawings,-Figure 1 shows the invention in side elevation; Fig. 2 is a section upon the line 2.2 of Fig. l; and Fig. 3 is a section on the line 33 of Fig. 1.

In carrying out the invention there is,pro-

vided a primary lever 1, one end 2 of which is reversely curved, as shown at -3, the extremity of the portion 2 being provided with a depression or seat 4, adapted to engage the rib of the tire. The intermediate portion of the primary lever 1 is flattened, as

shown at 5, and upon the outer edge of this flattened portion 5 there are ratchet teeth 6,

inclined toward the handle end 7 of the leye'r. Extended longitudinally of the primary lever 1 is a series of openings 8, these openings 8 being located opposite, the bases of the teeth 6. Y

The invention further includes an arched rim hook 9, one end 10 of which is provided with arms 11 terminating in angularly disposed lugs 12. The other end lflfif the arched rim hook 9 terminates-in armsis, these arms 15 extending across the flattened portion 5 of theprimary lever 1.

Disposed between the arms 15 of ,the'rim hook 9 is a secondary lever 16. A bolt 17 or'like connecting element is passed through the arms 15 of the rim hook 9,and through the secondary lever 16, adjacent one end of the said lever, the major portion of the secondary lever 16 extending free in the gen- 1. The construction is such that the" olt 17 may be disconnected from the secondary lever 16, whereupon the bolt may be inserted into any of the openings 8 in the primary lever 1, for the purpose of connecting the rim hook 9 directly to the lever 1.

Having thus described the invention, what is claimed is 1. A device of the class described comprising a primary lever; a rim hook extended transversely of the primary lever; and a secondary lever fulcrumed intermediate its ends in the hook and having a step by step engagement with the primary lever.

2. A device of the class described comprisinga primary lever; a rim hook extended transversely of the primary lever; 11 secondary lever having a step by step engagement with the primary lever; and a pin. pivotally connecting the secondary lever with the hook; there being openings in the primary lever, adapted toreceive the pin, to connect the hook directly with the primary lever,

the hook.

A device of the class described comprising a primary lever providedwith ratchet teeth in its edge; a IlIIl hook having arms straddling, and extending across thep'rimary lever; a secondary lever located between the arms of the hook, and havin a pawl adapted to engage with the rate et teeth; and a pin extended through the arms and through the secondary lever, there being openingsjn the primary lever adjacent the ratchet teeth, in which '0 enings the pin may be placed, to connect t .hook directly with the primar lever, when the secondary lever is remove from the hook.

In testimony that I claim the foregoing as myown, I have hereto aflixed my signature in the presence of two witnesses.
